RESUMEN

PURPOSE: Many series have compared voice quality after radiotherapy or surgery for cT1 glottic carcinoma. Different meta-analyses identify better results for radiotherapy while others do not identify any difference, some finally find a superiority of surgery. The purpose of this study was to compare the voice quality in the long term of patients who underwent transoral surgery versus exclusive irradiation for the treatment of cT1 glottic carcinoma. MATERIAL AND METHODS: The VOQUAL study was a pilot comparative multicenter cross-sectional study. The primary endpoint was the Voice Handicap Index comparison between two groups (radiotherapy or surgery). The voice assessment also consisted in the heteroevaluation of voice quality by the Grade, Roughness, Breathness, Asthenia, and Strain rating scale reported by Hirano. RESULTS: The study included 41 adult patients with cT1 carcinoma of the vocal cord treated by cordectomy or exclusive radiation in two oncologic centers. The median Voice Handicap Index value was 20 [8; 32.5] in the surgery group and 10 [4; 18.5] in the radiotherapy group. There was no statistically significant difference between the median values and the various components F, P and E of the questionnaire (P=0.1585). The median value of the numeric dysphonia Grade, Roughness, Breathness, Asthenia, and Strain scale was 2 [0; 5] in the surgery group and 2 [0.25; 3.75] in the radiotherapy group. There was no statistically significant difference between these values (P=0.78). CONCLUSION: Our study did not show any significant difference on the primary endpoints of Voice Handicap Index and Grade, Roughness, Breathness, Asthenia, and Strain scores. LEVEL OF EVIDENCE: III. CLINICAL TRIAL REGISTRATION: The VOQUAL study was registered on the ClinicalTrials.gov platform under the number NCT04447456, in July 2020.

RESUMEN

OBJECTIVE: To explore the clinical effectiveness of reconstructing laryngeal function using thyroid cartilage fenestration and "draw-out" resection, supplemented by internal fixation with titanium microplates in early glottic carcinoma. METHODS: Data from 99 patients with glottic carcinoma treated in the Second Affiliated Hospital of Fujian Medical University between January 2014 and September 2021 were retrospectively analyzed. Forty-eight patients who underwent thyroid cartilage fenestration and resection followed by internal fixation with titanium microplates for laryngeal function reconstruction were assigned to the thyroid cartilage fenestration group (TCF group), while the other 51 patients who underwent sternohyoid muscle and fascia repair for laryngeal function reconstruction were assigned to the sternohyoid muscle repair group (SMR group). Patients were followed up for 1-8 years. Data on postoperative phonatory function, respiratory function, swallowing function, and survival status were collected. RESULTS: Compared to the SMR group, patients in the TCF group showed better postoperative recovery in phonatory function and verbal communication (all P<0.05). In the TCF group, patients demonstrated stable respiration and the extubation rate was 100.00%, which was significantly higher than 82.35% in the SMR group (P<0.05). Patients in both groups showed good postoperative recovery of swallowing function (P>0.05). CONCLUSION: One-stage reconstruction of laryngeal function by thyroid cartilage fenestration and "draw-out" resection with adjuvant internal titanium microplate fixation in early glottic carcinoma demonstrates good postoperative recovery and good preservation of the laryngeal function.

RESUMEN

BACKGROUND: The aim of this study is to examine the outcomes of an accelerated fractionated irradiation for N0 glottic carcinoma. METHODS: In this retrospective analysis, 29 patients with N0 glottic carcinoma treated by radiation therapy were enrolled. Thirteen patients had T1a disease, six had T1b disease, and ten had T2 disease. A fractional dose of 2.1 Gy was administered to seven patients. The total doses were 65.1 and 67.2 Gy in four and three patients, respectively. A fractional dose of 2.25 Gy was administered to 22 patients. The total doses were 63 and 67.5 Gy in 21 patients and 1 patient with T2 disease, respectively. Additionally, 13 patients underwent the use of TS-1 (80-100 mg per day). RESULTS: The median follow-up period was 33 months, and the 3-year local control rate was 95.6%. No patient had a lymph node or distant recurrence. As acute adverse events, grades 2 and 3 dermatitis were observed in 18 patients and 1 patient, and grades 2 and 3 mucositis were observed in 15 patients and 1 patient. As a late adverse event, one patient required tracheotomy because of laryngeal edema occurring. CONCLUSIONS: Accelerated fractionated irradiation may be an option in the radiation therapy of N0 glottic carcinoma because of its ability to shorten the treatment time.

RESUMEN

PURPOSE: In early glottic squamous cell carcinoma, similar results have been described in terms of disease control between transoral laser microsurgery (TLM) and radiation therapy (RT). During the past two decades, several studies compared subjective vocal outcomes of exclusive RT with those of TLM, showing a trend towards improving results for TLM over time. However, the objective differences in terms of spectro-acoustic voice parameters between exclusive RT and TLM have been less frequently investigated. The aim of this systematic review with meta-analysis was to evaluate voice quality after TLM and RT treatment for early glottic carcinoma, based on acoustic analysis parameters including jitter, shimmer, noise to harmonic ratio, fundamental frequency and maximum phonation time. MATERIAL AND METHODS: A search of the English published literature was conducted on the Pubmed, Scopus and Cochrane databases following PRISMA guidelines. RESULTS: A total of 441 titles were retrieved from the search. After full-text screening and application of inclusion/exclusion criteria, 12 articles were included. We found no significant differences between TLM and RT treatment in the considered acoustic analysis parameters, except for Shimmer, with more favorable values reported in the RT group. CONCLUSIONS: Considering the spread of the disease and expecting an improvement in long-term survival over time, well-designed and multicentric studies involving larger populations with a long-term follow up are mandatory to better assess objective voice outcomes in terms of spectro-acoustic voice parameters.

RESUMEN

Objective:To investigate the effect of acellular dermal matrix in preventing laryngeal stenosis in glottic carcinoma patients. Methods:Fifty-five patients with glottic carcinoma（T2, T3） from February 2018 to December 2022 were divided into experimental group（28 cases） and control group（27 cases） according to their wishes. Acellular dermal matrix was placed in the operation cavity in the experimental group after laryngofission, while control group 12 cases were sutured by pulling the upper and lower edges, 15 cases were repaired with sternohyoid muscle fascia flap. Results:In the experimental group, 1 case had laryngeal stenosis caused by laryngeal mucosa swelling after operation, and extubated successfully after symptomatic treatment. In the control group, 7 cases had laryngeal stenosis after operation, of which 3 cases were caused by granulation tissue hyperplasia in laryngeal cavity, and extubated after symptomatic treatment. 2 cases extubated after operation suffered from progressive dyspnea during radiotherapy, and underwent tracheotomy again, extubation successful after treatment. 2 cases caused by laryngeal mucosa swelling, after symptomatic treatment, one case was successfully extubated, and one case had long-term intubation. The laryngeal stenosis rate of the experimental group was 3.6%（1/28） , which was lower than control group 25.9%（7/27）, and the therapeutic effect of the experimental group was significantly better than control group （χ²=5.526, P=0.019）. Conclusion:Implanting acellular dermal matrix in the operation cavity of glottic carcinoma can reduce the occurrence of laryngeal stenosis and have satisfactory preventive effect on laryngeal stenosis.

RESUMEN

The objective of this study was to demonstrate the oncologic efficacy of awake endoscopic laryngeal surgery in the treatment of T1-T2 glottic carcinoma. This is a retrospective study. Seventy-one patients with early glottic carcinoma (T1a- 26, T1b- 18, T2- 27) who underwent awake flexible endoscopic laryngeal surgery under local anesthesia and mild intravenous sedation were included in the study. In 64 cases (90.1%) only endoscopic tumor ablation by Nd:YAG laser (in 32.4% of cases being preceded by diathermy snare excision) was performed, and in 7 T2 cases postoperative radiotherapy was also offered. There were no complications during or after the endoscopic surgery. Ultimate control of disease, including salvage treatment, was obtained in 67 patients (94.4%). Cure without recurrence was achieved in 60 cases (84.5%). Local control without salvage radiotherapy or/and open surgery was achieved in 64 (90.1%) patients. Larynx preservation was obtained in 66 (93.0%) cases. At 5 years from the beginning of endoscopic treatment, 74.6% of the patients were alive and free of disease. The best results were obtained in the T1a group of treated patients, all the patients being free of disease with the preserved larynx. Awake endoscopic laryngeal surgery is a safe and oncologically efficient method of treatment of early glottic carcinoma that can be considered as an alternative to the traditional approach, primarily, for patients with risks/contraindications for radiotherapy, general anesthesia, and transoral microsurgery, and also for the patients who prefer to avoid general anesthesia with its related risks and would rather choose office-based laryngeal surgery.

RESUMEN

Transoral laser microsurgery represents the primary surgical modality for early laryngeal cancers with oncologic outcomes equivalent to radiotherapy. Accurate tumor mapping and margin assessment can be difficult, however, particularly during piecemeal or ablative resections, and for tumors with a wider geographic footprint. Tumor-targeted fluorescence-guided surgery in patients with head and neck cancer has empirically improved tumor and margin identification; this case details, for the first time, a fluorescence-guided surgical resection of a T2N0M0 transglottic tumor using panitumumab-IRDye800, an epidermal growth factor receptor monoclonal antibody covalently linked to near-infrared (NIR) dye.

RESUMEN

The objective of this study was to determine the outcomes of radical radiotherapy for early glottic squamous cell carcinoma (EGSCC) with the policy of increasing the fraction size during radiotherapy when the overall treatment time (OTT) was expected to be prolonged. Patients diagnosed with clinical T1-2N0M0 EGSCC, who were treated with radical radiotherapy between 2008 and 2019 at Hokkaido University Hospital, were included. Patients received 66 Gy in 33 fractions for T1 disease and 70 Gy in 35 fractions for T2 disease as our standard regimen (usual group [UG]). If the OTT was expected to extend for >1 week, the dose fraction size was increased from 2.0 to 2.5 Gy from the beginning or during radiotherapy (adjusted group [AG]). At this time, we performed a statistical analysis between UG and AG. In total, 116 patients were identified, and the treatment schedules of 29 patients were adjusted. The median follow-up was 60.9 months. In the T1 group, the cumulative 5-year local failure rate was 12.0% in the AG and 15.4% in the UG, and in the T2 group, the rate was 40.7% in the AG and 25.3% in the UG. There were no significant differences between the AG and UG. Similarly, no significant differences were observed for overall survival and progression-free survival rates. Our single-institutional retrospective analysis of EGSCC patients suggested that a method of adjusting the radiotherapy schedule to increase fraction size from the beginning or during the course may be effective in maintaining treatment outcomes.

RESUMEN

Laryngeal carcinoma is the most common site of malignancy in head and neck region worldwide. Surgical options are limited in cases of laryngeal malignancy and moajority of cases are treated with chemoradiotherapy. Targeted therapy is an evolving novel approach to treat laryngeal carcinoma. The study was conducted to evaluate the role of PTEN, EGF and HER2 in early glottic squamous cell carcinoma cases. 52 samples of early glottis carcoinoma were collected in UCMS and GTB hospital, New Delhi after patients had undergone CO2 laser excision at the centre. Histopathologic and IHC examination was conducted on the specimen for PTEN, EGFR and HER2 molecules. PTEN was negative in 82.69% cases compared to the stroma with three year local control rate of 72.09%. EGFR was positive in 67.31% samples with three year local control rate of 68.57%. HER2 was negative in all the samples. PTEN and EGFR can be used as prognostic markers as well as novel agents for targeted therapy in the future.

RESUMEN

One of the main issues in early-stage glottic carcinoma management is the voice quality following different types of treatment modalities. In type 3 and 4 transoral laser cordectomies, the voice outcomes can show significant differences due to the extent of the vocal muscle resection. This study aims to compare the voice quality in patients who underwent type 3 and 4 laser cordectomy for early-stage glottic carcinoma. A total of 30 patients who underwent type 3 (15 patients) and type 4 (15 patients) laser cordectomy for T1a glottic carcinoma between May 2018 and 2020 were included in this retrospective comparative study. Electroacoustic voice analysis and Voice Handicap Index-10 were performed in the postoperative twelfth month and the outcomes were compared between two laser cordectomy groups. The mean age of all patients was 48.6 ± 4.2 years. Noise-to-harmonic ratio, jitter, shimmer, pitch perturbation quotient and amplitude perturbation quotient values were significantly different between two groups (p < 0.05). Fundamental frequency and Voice Handicap Index-10 scores showed no statistically significant difference (p > 0.05). This study reports significantly better results for type 3 against type 4 laser cordectomy by means of objective voice analysis outcomes, except fundamental frequency. On the other hand, self-reported subjective analysis showed very similar results for both groups. Further studies combining data with multiple objective and subjective analyses with larger patient series and longer follow-up are warranted.

RESUMEN

The local control rates of T1 bulky and T2 glottic carcinoma treated via radiation therapy alone are unsatisfactory; thus, we aimed to evaluate the efficacy and safety of our treatment protocol for early glottic carcinoma. Patients with early glottic squamous cell carcinoma treated via radiation therapy from January 2007 to November 2019 were reviewed. Patients were treated with: 63-67.5 Gy/28-30 fractions of radiation therapy alone for T1 non-bulky; concurrent chemoradiotherapy with S-1 and 60 Gy/30 fractions for T1 bulky and T2 favorable; and concurrent chemoradiotherapy with high-dose cisplatin and 66-70 Gy/33-35 fractions for T2 unfavorable glottic carcinoma. Local failure rates were estimated using the cumulative incidence function, overall and disease specific survival rates were estimated using Kaplan-Meier analysis, and adverse events were evaluated. Eighty patients were analyzed; the median age was 69.5 (range, 26-90) years, the median follow-up time for survivors was 40.1 (range, 1.9-128.4) months, and the 3-year local failure, disease specific survival, and overall survival rates were 5.8%, 98.3%, and 94.4%, respectively. In T1 bulky and T2 cases, the local failure rate was significantly lower in the concurrent chemoradiotherapy than in the radiation therapy alone group. Grade 3 acute dermatitis and mucositis were noted in nine and four patients, respectively. There were no acute adverse events of Grade 4 or higher, or late adverse events of Grade 2 or higher. The treatment protocol was effective and well-tolerated; thus, the efficacy of concurrent chemoradiotherapy was suggested in T1 bulky and T2 cases.

RESUMEN

Laser laryngectomy is a minimally invasive surgical technique that offers advantages such as precise and limited resections, magnification of the surgical field by microscopy, and improved patient outcomes. However, it is not without risks, and intraoperative complications have been reported, including cervical-cutaneous emphysema. This case report presents a rare complication of cervical-cutaneous emphysema after laser laryngectomy occurring in a 57-year-old patient with glottic carcinoma. The patient underwent laser cordectomy, and after an uneventful procedure, the patient experienced an intense coughing episode followed by swelling and progressive emphysema. The patient was kept under surveillance in the intensive care unit and received ampicillin sulbactam, protective orotracheal intubation, and voice rest. The patient had a good clinical evolution, and the emphysema resolved within 8-10 days. This case highlights the importance of prompt recognition and management of complications that can arise from laser laryngectomy. Although this technique offers several advantages, it is not risk-free, and intraoperative complications can occur. As such, careful consideration and patient selection are important to minimize the risks and achieve successful outcomes.

RESUMEN

BACKGROUND: To investigate the outcomes of using the residual thyroid cartilage for laryngeal function reconstruction in early glottic laryngeal carcinoma. METHODS: From March 2017 to June 2022, 21 patients with glottic carcinoma who underwent laryngeal function reconstruction were analyzed retrospectively. The operation was performed under general anesthesia. Reconstruction of ipsilateral hemilarynx defect by downward movement of ipsilateral residual thyroid cartilage plate. During the follow-up period, the laryngeal function and tumor recurrence were evaluated. RESULTS: otally 20 male patients and 1 female patient were enrolled in this study. Of the 20 initial primary tumors, there were 6 patients with T1N0M0 stage, 12 ones with T2N0M0 stage, 1 with T1N1M0 stage, 1 with T3N0M0 stage, and 1 with T2N1M0 stage. The patient with recurrent tumor was T3N1M0 stage. The follow-up time ranged from 9 to 63 months. All patients were healed by first intention after surgery. All patients without laryngeal stenosis were removed from tracheotomy tube. So far, all patients have good laryngeal function. One patient relapsed at the last follow-up. CONCLUSION: It is safe to repair hemilarynx defect with residual thyroid cartilage plate on the affected side, and it is an important choice for laryngeal function reconstruction after vertical partial laryngectomy.

RESUMEN

BACKGROUND: T2N0M0 glottic laryngeal squamous cell carcinoma (LSCC) is a common type of laryngeal cancer. OBJECTIVES: The objective of this research was to assess the predictive value of tumor size for the rates of overall survival (OS) and disease-free survival (DFS) as determined by postoperative pathological examination in patients with T2 LSCC. METHODS: A retrospective study was conducted on 535 successive patients with T2 glottic LSCC who underwent operation from 2005 to 2010. The effect of tumor size on OS and DFS results was evaluated by the affected area. RESULTS: Of the cohort, 528 (98.7%) were male, and 7 (1.3%) were female, with an average age of 60.1 ± 9.4 years. The 10-year DFS and OS rates were 72.1% and 76.3%, respectively. The tumor diameter and area cut-off values that best discriminated OS and DFS rates were 1.35 cm and 1 cm2, respectively. Patients with glottis carcinoma with a longer tumor diameter and larger tumor area had inferior OS and DFS rates. Tumor diameter and tumor area were independent predictive factors for the rates of OS and DFS in patients with T2 glottic LSCC. CONCLUSION AND SIGNIFICANCE: This research showed that patients with T2 glottic LSCC with a carcinoma diameter >1.35 cm or a tumor area >1 cm2 have worse survival outcomes. These factors independently predict survival outcomes in patients.

RESUMEN

BACKGROUND: Laryngeal carcinomas cause vocal cord (VC) mobility problems. Other than evaluation through flexible laryngoscopy, rare reports concerning CT findings for the motion of the VC or arytenoid cartilage (AC) are found. AIMS/OBJECTIVES: To explore a novel evaluation of the mobility of the AC in glottic carcinoma. MATERIAL AND METHODS: In 39 patients with glottic carcinoma grouped upon lesion locations and AC mobilities, laryngeal CT scans were collected during inspiration and phonation. AC static position and motion data were compared between paired lesion and control sides. RESULTS: No significant difference showed in the group with glottic carcinoma invading the anterior 2/3 of VC. In the abnormal mobility group, significant AC position changes and weaker motion of most measurements were proved on the lesion side. Lesion invading the posterior 1/3 of VC also resulted in an adducted, medially rotated and forward-tilted AC, rotation of axial angle (RAA) was the only motion item that decreased significantly. CONCLUSIONS AND SIGNIFICANCE: In most glottic cancer cases, CT and laryngoscope had similar judgments for AC mobility. For lesions extending to the cartilaginous VC with laryngoscopically confirmed normal mobility, CT measurement of RAA showed the feasibility of being an indicator for the earliest motion problem.

RESUMEN

OBJECTIVE: Anterior commissure (AC) involvement is an unfavorable factor for transoral laser microsurgery (TLM) treatment of early glottic carcinoma (EGC). This study aimed to evaluate the therapeutic efficacy of TLM treatment for EGC with AC involvement. METHODS: From 2008 to 2017, 177 patients with T1-T2 EGC with AC involvement were retrospectively included and divided into the TLM group (n=115) receiving CO2 laser TLM and the control group undergoing open surgery (n=62). The survival outcomes, postoperative complications, laryngeal preservation rate, recurrence and the phonological results were compared between groups. RESULT: The TLM group had significantly reduced hospital stay, hospitalization costs, and intraoperative blood loss as compared with the control group. The tracheotomy rate was significantly higher in the control group (96.8% vs. 0%). The 5-year overall survival (OS) was 89.6% and 85.5% in the TLM group and control group, respectively. Log-rank test showed no difference in survival rate between the two groups. There was no significant difference in laryngeal preservation rate and overall recurrence rate between groups. In postoperative vocal function evaluation, there were significant differences in the overall grade (G), the roughness (R), the breathiness (B), Voice Handicap Index-10 (VHI-10), Jitter, Shimmer, noise/harmonic ratio (NHR), maximum phonation time (MPT), phonation threshold pressure (PTP) between the two groups. CONCLUSION: For EGC with AC involvement, TLM has similar survival outcomes with the open surgery, but has better postoperative voice outcomes. Meanwhile, TLM can effectively reduce intraoperative blood loss, hospitalization time, hospitalization costs and postoperative complications.

RESUMEN

Background: Treatments for cT1-2, N0 glottic squamous cell carcinoma (GLSCC) include endoscopic resection, open surgery, and radiotherapy. The purpose of this study was to compare the outcomes of three treatment modalities and provide reference data for treatment selection. Methods: In all, 4274 patients with cT1-2, N0 GLSCC underwent these three treatment modalities from 2004 to 2015 were identified from the Surveillance, Epidemiology, and End Results-18 database. Overall survival (OS) and disease-specific survival (DSS) of patients treated with the three modalities were compared. Results: In the entire cohort, there were no significant differences in 5-year OS and 5-year DSS among the three treatment groups. In subgroup analyses based on stage and age, endoscopic resection provided significantly better 5-year survival than radiotherapy for cT1, N0 patients aged <65 years, with an OS rate of 89.0% vs. 82.3% (p = 0.009) and a DSS rate of 95.6% vs. 88.2% (p = 0.021). For 5-year DSS, open surgery also had better outcomes than patients who received radiotherapy (5-year DSS: 98.5% vs. 88.2%, respectively; p = 0.046). Conclusions: To summarize, for cT1, N0 GLSCC patients younger than 65 years, surgical treatment (either endoscopic or open) appears to be superior to the radiotherapy, and endoscopic resection should probably be the first consideration.

RESUMEN

Aim: Laryngeal cancer is a common form of head and neck cancer in Vietnam where the current treatment is surgery. Subtotal laryngectomy with epiglottic reconstruction, a conservative surgery, allows removal of anterior commissure including thyroid cartilage and paraglottic space and provides a maximum restoration of the anatomical structure of the larynx. Purpose: To evaluate the results, the safety and effectiveness of patients who were treated with subtotal laryngectomy with epiglottic reconstruction. Material and Method: From January 2012 to July 2017, 42 patients (41 male, 1 female, median age 55.6 years, range 38-75 years) were diagnosed with glottic carcinomas at Vietnam National ENT Hospital, where they underwent a subtotal laryngectomy with epiglottic reconstruction. Results: Thirty-one patients (73.8%) had T2 glottic carcinoma, 4 (9.5%) T3 glottic carcinoma, and 12 (25.6%) had neck dissection. The arytenoid cartilage on the tumor-bearing side was resected in 11 patients (26.2%). Functional ipsilateral neck dissection was performed in 30 patients. Positive lymph node of stage T2 was 1/31 (3.2%). Postoperative histopathologic examination showed a tumour free of resection margin in 41 patients (97.6%). Only one post-operative complication occurred with bleeding 24 hours after surgery. There was no mortality. The 3- and 5-year overall survival rates were 97.6% and 85.7%, respectively. The rate of local control was 92.9%. Conclusion: Subtotal laryngectomy with epiglottic reconstruction was performed mostly for T2 and certain T3 glottic carcinomas when there is difficult to safely remove the tumour with transoral laser microsurgery. This surgery appears to be effective for the overall survival and has potential in clinical practice for treating moderate glottic carcinoma.

RESUMEN

Laryngeal carcinoma is one of the most common tumors of the head and neck, just after skin cancer. Alongside open surgery, transoral endoscopic laser surgery (TOLS) has become widespread as a treatment method. Our aim was to assess the efficacy of transoral laser cordectomy in a group of patients with early glottic carcinoma. We retrospectively analyzed data on 131 patients who underwent TOLS in the 2017-2021 period. We divided patients into groups according to tumor stage and type of cordectomy performed, and compared outcomes between the groups. Our results revealed a higher number of patients in the group with Tis and T1a than in those with T1b and T2 who underwent type III cordectomy, and also a higher number of those for whom outpatient follow-ups were sufficient after surgery in the same group. We did not observe significant difference in outcomes according to cordectomy type except for type V (a-d), where a higher number of patients had to undergo radiotherapy. This study underlines the importance of careful patient selection for TOLS, as well as the need for close cooperation with pathology and radiology specialists to ensure optimal approach and extent of surgery for each individual patient. It also displayed TOLS as a sound therapeutic option for early stages of glottic carcinoma but also indicated the need for similar studies in a larger number of patients to elucidate the effectiveness in certain glottis areas.

RESUMEN

BACKGROUND/AIM: We retrospectively evaluated the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) with docetaxel, cisplatin, and 5-fluorouracil (TPF) for T3 N0 glottic carcinoma without vocal cord fixation. PATIENTS AND METHODS: Twenty-five patients underwent TPF-CCRT without elective nodal irradiaion (ENI). After the RT of 40 Gy, five patients (20%) without tumor regression underwent surgery. Others underwent RT with a median total dose of 66 Gy. RESULTS: Of the five patients who underwent surgery after the RT of 40 Gy, two showed residual carcinoma pathologically and the other three were confirmed to have complete pathological response to the treatment. The 5-year local control rate was 87%. No patients exhibited regional failure. No acute toxicities of grade 5 or late toxicities ≥grade 3 were observed. CONCLUSION: TPF-CCRT provides excellent tumor control with acceptable toxicities. CCRT while omitting ENI is a reasonable approach for T3 N0 glottic carcinoma without vocal cord fixation.
